John’s scene in heaven

Immediately I was in the Spirit, and a throne was standing in heaven with someone seated on it!
And the one seated on it was like jasper and carnelian in appearance, and a rainbow looking like it was made of emerald encircled the throne.
In a circle around the throne were twenty-four other thrones, and seated on those thrones were twenty-four elders. They were dressed in white clothing and had golden crowns on their heads.
From the throne came out flashes of lightning and roaring and crashes of thunder. Seven flaming torches, which are the seven spirits of God, were burning in front of the throne
and in front of the throne was something like a sea of glass, like crystal. In the middle of the throne and around the throne were four living creatures full of eyes in front and in back.
